I can't start my Overleaf server

Hi, i'm only a simple user trying to write my master thesis, but suddenly the electricity cut off and it seems like I lost everything. Can anyone help me?

====== Warnings ======
! Docker daemon is not running
! Sibling containers are not available in Community Edition, which is intended for use in environments where all users are trusted. Community Edition is not appropriate for scenarios where isolation of users is required. Sibling containers are offered as part of our Server Pro offering and you can read more about the differences at https://www.overleaf.com/for/enterprises/features. Set SIBLING_CONTAINERS_ENABLED=false in config/overleaf.rc to continue using insecure in-container compiles.
====== End ======

The report only names bin/doctor and config/overleaf.rc; begin by reading the diagnostic entry point and checking how it reports Docker daemon status. No source file, test, requested change, or definition of done is provided, so the issue needs maintainer clarification before a newcomer can implement it.
